Saracens will toss a coin to decide whether Richard Wigglesworth or Neil de Kock start at scrum-half in Saturday's Premiership final against Leicester.
The pair have been rotated all season, with Wigglesworth edging De Kock's number of appearances 31 to 26.
"We made a very deliberate decision that we wouldn't change anything for semi-final or final," Sarries boss Mark McCall told BBC Three Counties Radio.
"In both those games there's been the toss of a coin."
It was 28-year-old Wigglesworth who got the nod in the semi-final win over Gloucester, but he was replaced by his fellow number nine after 59 minutes.
And the pair will once again call heads or tails to decide who steps out at Twickenham to face the Tigers.
"We're very fortunate we've got two world class scrum-halves who have rotated evenly throughout the year," added McCall.
"They'll both contribute in the final, they're evenly matched and we don't have a number one and we weren't going to change that policy for the final."
Competition for places has been a theme of Saracens' season, with 43 different players being used across their Premiership campaign.
Youngsters such as Alex Goode, Owen Farrell, James Short and Andy Saull have come to the fore and impressed captain Steve Borthwick.
"We've got some brilliant youngsters who are part of this club," said McCall.
"We've used 43 players in our Premiership season which shows the strength in depth we have.
"For all the staff, the players, the supporters and chairman I really hope we can get success for them this weekend."
Saracens full-back Goode told BBC Three Counties Radio that they have improved since their defeat in last season's final.
"We've learned a lot from last year, we're a very similar squad, with a few additions, and I think we've grown a lot," he said.
"We were perhaps a bit too happy to be in the final and didn't believe in ourselves enough in the final.
"We obviously tried to win it but maybe deep down we were so happy with the fairytale it had been that we perhaps didn't believe in ourselves.
